Understanding Quantum Computing

Before delving into quantum machine learning, it is essential to grasp the fundamentals of quantum computing. Traditional computers process information using bits, which can represent either a 0 or a 1. In contrast, quantum computers leverage quantum bits, or qubits, which can exist in a superposition of states, allowing for simultaneous representation of 0 and 1.

Furthermore, qubits can be entangled, meaning the state of one qubit can be correlated with the state of another, regardless of their physical distance. This property enables quantum computers to perform parallel computations and solve certain problems exponentially faster than classical computers.
